IMPROVEMENT IN MANURE-SPREADERS.

Specification forming part of Letters Patent No. 190,290, dated May 1,1877 5 application filed February 28, 1877.

To all whom it may concern 7 Be it known that I, JosEPH SARGENT of Magog, in the county of Stanstead, Canada, have invented certain new and useful Improvements in Manure-Spreaders; and .I do hereby declare that the following is a full, clear, and exact description thereof,

which will enable others skilled in the art to whichit appertains to .makeand use the same,

reference being had to the accompanying drawings, and to the letters of reference marked thfi eon, which form a part of this of the same, showing the right-hand side, a

portion of one wheel being represented as removed. Fig. .3 is a plan view of the same,

showing the floor partly run out, in order to more fully show the mechanism below; Fig.

,4 isa rear end view of the same, portions of the drill .attachment being-represented as broken away, to show the arrangement of the machinery beyond.

The object of this invention is to provide a farm wagon or cart with a movable floor composed of slats secured to an endless belt or chain. 7 To the foremost slat an end board is secured, which, when the machine is in for ward motion, moves, by suitable gearing, slowly to the rear, thus propelling the material that may be loaded in the vehicle against a rotating toothed drum, which pulverizes and evenly spreads the load on the ground behind. The labor of unloading manure or other material is thus avoided and the process carried out much more rapidly and perfectly.

A in the drawing represents the box or body of the machine, within which the load is placed. B is the endless belt or chain, about one-half of which is made horizontally flat, with links corresponding in length to the'width of the slats that comprise the floor O, to which they r are contiguously secured. The endless belt or chain incloses the two pulleys which stretch and guide it-one, a, at the rear of the machine, the other, 0, near the forward part, as is clearly shown in Figs. 1 and 2. The pulley a is hexagonal in form, although it may be made octagonal, if desired. This pulley is provided with small projections in each of its faces, which; fit into corresponding cavities or holes in the belt or chainB,'andis oun-ted on a shaft, e, which extends to the left to the outside of the body A, where :it carries a gearwheel, f, the teeth of which engage with the spiral thread of a worm-gear, g, mounted on a-shaft,.h. The bevel-gear wheel 5 is also mounted on the shaft It, which has its forward bearing upon or near the axle F.- This wheel t'engages with a larger bevel-gear w-heel,j, secured to, and revolving with, the hub of the wheel E. Thus, it will be seen, the floor G derives motion, when ingear, from the wheel E.

The pulley .c is made to fit the links of the belt or chain B, and is mounted on a shaft, w,

which extends to the left alittle beyond the frame-work of the body A, where it carries a crank, e, the use of which will hereinafter be explained. y I

G is the tongue or pole, represented as broken oil, which is made forked to permit the passage of the belt or chain B. It also carries a brace, l, perforated with holesin the ordinary manner,,for the purpose of adjusting the inclination of the body A.

The two middle timbers d d of the frame of the machine carry small pulleys-an, which support the floor 0 and enable i to move easily. i

Dis the toothed drum or heater, a portion of the teeth of which are made knife-edged, for the purpose of more efl'ectually cutting and pulverizing turf, roots, or strawy manure. The comb 1 is furnished with spring-teeth T, which prevent the passage of large lumps, which, being held against the toothed drum D by the said comb, becomes thoroughly pul verized. Upon one end of the axle of the toothed drum a pinion, k, is secured, the teeth of which mesh into teeth of a larger gearwheel, u. The hub of this wheel is inclosed by, and made to fit the links of, a chain, 8. This chain also incloses a larger chaimwheel, t, the hub of which revolves upon and encircles a portion of the axle F. When it is desired to put the machinery of this side in motion the chain-wheel tis made to revolve with the wheel E by means of a clutch, 0, upon the hub of said wheel. This clutch is operated by a forked lever, 00, pivoted at b, and jointed to a handle, m, at the forward part of the machine, as is clearly shown in Fig. 3. The handle extends to the left, so as to be withineasy reach of the operator, and is provided with a catch, g, which looks the clutch 0 in or out of engagement with the spokes of the wheel t, as desired. the lever ac is made thin at j, Fig. 3, so as to In order to insure this engagement cal play, and its rear end, when in use, rests beneath the catch of a spring, 2.

One bearing, d, of the toothed drum D, is pivoted at e in such amanner that when too much pressure is brought to bear on the for- -ward side of the said toothed drum this hearing will be forced back, flexing the springf, and at the same time, by means of the coupling g, drawing the spring 2 away from contact with the lever J, when the worm-gear 9 will be disengaged with the gear-wheel f, thus throwing the machinery of this side out of gear, and preventing damage.

To the foremost slat of the floor O is secured the end-board h, which has a projectionyl', on its upper left-hand corner, the object of which is this: When the load is discharged the projection strikes the upper extremity of the spring z, forcing it away from the lever J, thus liberating it, with the result before described.

The load having been discharged, the floor (J is brought to its original position by revolving the crank 0, when it can be locked by a pin, m,.Fig. l.

The machine having been loaded and taken to the place of deposit is put in gear by two movements, one being by operating the clutch o by means of the handle m, as before de scribed, and the other by raising the forward end of the lever J until the opposite end is depressed suificiently to engage with the catch on the spring 2. Should the spiral thread of the worm glodgeupon the points of the teeth of the wheel f, the pivot in the lever J will rise'in the slot in the standard a. The forward end of the said lever is now bent down below the hole u. when the pin m is withdrawn from before the crank e, and inserted in the hole n, thus holding the lever J in position. The machine being in motion the worm 9 revolves until it drops in gear with the wheelf, when the floor G will be propelled toward the drum D, which, being also in motion, automatically unloads the machine.

The drill attachment H can be put on the machine when it may be desired to deposit the manure in drills or rows. The chutes q vand q are adjustable, so as to admit of the drills being deposited at various distances apart. To effect this adjustment the bolt It is made to draw the opposing'walls of the drill attachment toward each other, thus pressing them upon the edges of the middle chutes q, and holding them firmly in the position in which they may be placed. The

chutes q are held in the desired position by means of rods 1, which are inserted in holes for that purpose, as shown in Fig. 4..

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The yielding toothed roller D, in combination with the springf,couplingg, and spring z, substantially as and for the purpose set forth. V

2. The spring-lever J, connected to the gearing operating the slatted belt or bottom B G, in combination with the spring 2, coupling 9, roller D, pivoted bearing 01, and spring f substantially as and for the purpose set forth. 1

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.
